I find that physics is such a useful discipline. With a basic understanding, you can look at a number of magic solutions and figure out why they haven't happened yet.
Having said that, I think the traditional car is not out of gas so to speak.
With changes in weight, aerodynamics, energy recovery, diesel engines, improved fuel distribution and the like, I see us getting 50-60 MPG from regular cars in the not too distant future.
If you don' t think this is significant, think how much a cut of 4% in driving has impacted gas prices here in the US.
Imagine a cut of 25% or so in demand for gas???
